IMPROVEMENT IN SASH-LOCKS.

Specification forming part of Letters Patent No. 222,919, dated December 23, 1879; application filed April 24, 1879.

To all whom it may concern:

Be it known that I, THEODORE F. LEMAS- SENA, of Newark, New Jersey, have invented a new and useful Improvementin Sash-Locks, of which the following is a specification.

This invention is in the nature of an improvement upon means for looking or fastening windows and doors against intruders, and is more particularly adapted to the lockin g of the meeting-rails of window-sashes.

The invention consists in a normally retracted spring-bolt having a hook-shaped end or nose, and an operating-knob combined with a normally-thrown spring-bolt provided with a catch-piece adapted to engage with the nose of the other bolt and retain it in a locked position, and also having an operating-knob.

In the accompanying drawings illustrating 'my invention, Figure 1 is a perspective view of a portion of a window-frame and the meeting-rails of its sashes with my improved button applied. Fig. 2 is a perspective View of Fig. 3 is a perspective view of the locking-bolt portion. Fig. 4 is a central cross-section of the two portions in unlocked position in the sash-rails. Fig. 5 is a bottom plan view of the catch-bolt portion, and Fig. 6 a similar view of the engaging-bolt portion of the button. Fig. 7 is a similar view of the two portions locked together.

Within a suitable shell, A, adapted to be secured to a window-sash rail or elsewhere, I arrange a bolt, H, having a hook-shaped end piece, h. This bolt is thrown against the pressure of a spring, K, by means of a knob, J, secured in it. The shank of this knob extends through a transverse slot, I, in the shell, and connects with the bolt, substantially as indicated in Fig. 4.

The spring K may be coiled about a post, L, on the case or shell, and, acting upon the bolt H directly, or by contact with the shank of the knob, it holds the bolt normally retracted.

The end piece or nose, h, of the bolt-H works through an opening, a, in the face or flange b of the shell, to engage with its'guard, as hereinafter specified. v

The guard or catch-bolt portion is provided with a matching shell or case, A, through a longitudinal slot, B, in which the shank of a knob, 0, extends and connects with a bolt, D, which I herein term the catch-bolt. This bolt D is provided with catch-piece d, that works partly over an opening, 0, in the flange e, and with which the hook-shaped end piece or nose, h, of bolt H engages.

The bolt 1) is normally so held as that its catch-piece 01 shall be in or before the opening 0 by means of a spring, E, that may obtain its resilience by being coiled about a post, F, on

the shell.

When the meeting-rails of window-sashes, for instance, are brought opposite each other, as in Fig. 1 of the drawings, the two bolts will be in the positions indicated in Fig. 4. To look them together the knob J is moved toward knob 0, against the force of the spring K, and the bolt H, being thrown by this motion of knob J, its nose h will project through opening a into the opening 0 of shell A, and, pressing back the bolt D, will extend beyond the catch-piece d sufiiciently far to admit said catchpiece into a recess back'of it, when the spring of bolt D will throw said bolt and its catchpiece into engagement with the nose, thereby drawing the two portions of the button and the rails together, and securely locking the sashes, so that it will be impossible to unlock them from the outside.

If the bolt 1) should work hard in locking, the operation may be facilitated by working the bolt by hand through its knob 0.

To unlock the button or release the bolt H, it is only necessary to retract the bolt D through the lengthwise movement of the knob 0, when the bolt H is free to retract by the resilience of its spring.

What I claim is- The combination of the normally-retracted springbolt H, its hook-shaped end or nose h, and knob, with the normally-thrown spring bolt D, its catch-piece d and knob, substantially as and for the purpose described.
